WebDec 18, 2024 · DNA consists of two strands, arranged in a double helix. These strands are made up of subunits called nucleotides. Each nucleotide contains a phosphate, a 5-carbon sugar molecule and a nitrogenous base. RNA only has one strand, but like DNA, is made up of nucleotides. RNA strands are shorter than DNA strands. WebDescribe in words or use the draw tool and label (in detail) what a DNA molecule looks like. Think of the model created by Watson and Crick. Include the shape, structural components, and the types of bonds. The shape of a DNA molecule is a double helix. More known to be a X - Cross, or 2 crossing strands.
